Who was first frontal nude male?

The first known depiction of a frontal nude male in Western art is often attributed to the ancient Greek statue "KritiOS Boy," which dates back to around 480 BCE. However, in terms of Western art history, the "David" by Michelangelo, created in the early 16th century, is one of the most famous representations of a frontal nude male. In a broader cultural context, various ancient civilizations, including the Greeks and Romans, featured frontal male nudes in their art, but KritiOS Boy is considered one of the earliest examples.
